Iron rich volcanic rock that makes up much of the ocean floor is?
The volcanic rock that makes up most of the ocean floor is called sediment.
What type igneous rock makes up most of the ocean floor?
Basalt
Why might continents with an ocean between them have sinilarities?
Because the continents were once one large piece of land. As one large piece of land, there were no continents. Sections broke away over time, likely aided by the fact that the ocean floor is constantly expanding each year. Look up Pangea and see image in Related Links.
Is the ocean floor a good place for fossils to form?
A lot of shells of marine organisms wind up on the ocean floor. Bones do not last on the ocean floor, they get eaten. But shells can last.
What do you call the crust making up the continents?
The crust that makes up the continents, or land masses on Earth is called continental crust. The crust that makes up the oceans is called oceanic crust.
Do continents reach the bottom of the ocean?
They do touch the ocean floor. they're like a giant mound, and the beaches flow into the water.
What are the two types of crust that makes up the continents and ocean?
The two types of crust that make up the continents and ocean are the continental crust and the oceanic crust.
Iron rich volcanic rock that makes up much of the ocean floor is?
The volcanic rock that makes up most of the ocean floor is called sediment.
What evidence in rock supports the theory of seafloor spreading?
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.
What layer of the earth makes up these plates and what layer are these continents sliding on?
The plates on the top of the upper mantle are referred to as the lithosphere, which slides on the asthenosphere.well the mantle causes the continents to move on the ocean floor and sand it makes it slideyea know the crustti is i dont ge ehttt

A rock that makes up much of the ocean floor?
basalt
What crust makes up the ocean floor?
Oceanic crust.
What is two differences between the continental crust and oceanic crust?
The oceanic plate is thin, dense, and makes up the ocean floor. The continental plate is less-dense, thick, and make up the continents.
What rocks make up the continent floor?
The continental plate, which is made of granite rock, makes up the continents.
What type of rock makes up the ocean floor?
Primarily lime stone.
